Dynamics on the perfect kernel of higher rank generalized Baumslag-Solitar groups
Sasha Bontemps
In this article, we study the space of subgroups of non-amenable generalized Baumslag-Solitar groups (GBS groups) of rank , that is, groups acting cocompactly on an oriented tre…

Subgroup mixing in Baumslag-Solitar groups
Sasha Bontemps
In this article, we contribute to the study of the dynamics induced by the conjugation action on the space of subgroups of Baumslag-Solitar groups BS(m,n), via the mixing propertie…

Perfect kernel of generalized Baumslag-Solitar groups
Sasha Bontemps
In this article, we study the space of subgroups of generalized Baumslag-Solitar groups (GBS groups), that is, groups acting cocompactly on an oriented tree without inversion and w…
